TO ALL WHOM IT MAY CONCERN:

Be it known that L JUHN S WOOD, of Hartford, in the county of'Hartford, and State of Connecticut, have invented anew and improved Brick-Machine; and I do hereby declare that the following is a full, clear, and

, exact description thereof, which will cnahl'e others skilled in the art to make and use the same, rei'erence'heing had to the accompanying drawings, forming part of this specification.

Figure 1 represents a longitudinal vertical section of my improved brick-machine.

Figure 2 is a' side elevation ofthe same.

Figure 3 is a detail longitudinal verticalsection of the same.

Figure his a detail side view of the'same.

Similar letters of reference indicate corresponding parts. i

This invention relates to certain improvements in brick-machines, by means of which the pressure uponthe clay in the moulds can be regulated at will, by means of which the operation of the machine can be interrupted at once, whenever desired, without stopping the motion of the 'main driving-shaft, wherehy the grate will he enabled 'to yield to stones or other obstacles thatmay project from thc moulds, and whereby the gate -in front of themould-b'ox will also be automatically raised by such obstructions.

'lhe'invention' consists, first, in connecting an oscillatingdever,which is worked from the driving-shaft,

with a rock-shaft, that operates the presser by means of a toothed or notched bar, in such a manner, that, by

setting this bar, the-degree of oscillation of therock-shai't canlie increased or reduced at will, or-cven entirely stopped, so that by this means thepressermay he caused to compress the clay in the moulds more or less, or'to remain entirelyv stationary, without in the least varying or stopping'thc motion of thedriving-shaft.

The invention consists, second, in hing'ing the grate at its inner side, so that it maybe raised in front by stones or other, obstructions projecting from the sliding moulds, whereby the continued motion of the machine is permitted, even if such obstructions should accidentally have found their way into the moulds;

The invention, finally, consists in arranging, in combination with the hinged grate, a sliding gate, which rests with projecting pins or lugs upon the front of the grate, and which is therefore raised with and by the grate,v to allow the discharge of the mould, with its projecting obstructions.

A, in the drawing, represents the frame of an ordinarycr suitable brick-machine, in which a vertical shaft, B, carrying stirrers O C, has its bearings.

D represents the mould-box, arranged in front of the mud-mill E, and receiving the clay from the same through an aperture, a, in the front wall of the mud-mill. I I

F represents the reciprocating prcsscr, arranged as-cover of the mould-box, and suspended from a horizon tal bar, 6, which slides in slottedplates c c, that-project from the ends of the stationary mould-box. By means of connecting-rods cl d, the bar 6 is connected with, cranks e e, which project from a horizontal rock-shaft, G, that has its hearings in the lower part of the frame A. 7

On the rock-shaft G is also arranged a crank, from the side of which a pin, g, projects, as shown in figst 2 and 4. it is a bar, turning'loose on the shaft G, and to its free end is pivoted'a toothed o'r notched lever, H,

as shown. On the shaft G turns also, loosely, a bar, 2', which is at one end connected, by means of a rod, j, with a. crank, K, projecting from a horizontal shaft, I that receives rotary motion, by means of gearing or otherrise, from the driring-shaft 13.

From the bar i-project respectively, in front and rear of the shaft G, lugsl and m, which have bent-in or broadened ends. When the lever H is fitted upon the pin 9, so that thatpin fits into one of the notches in the lever, and when, then, the shaft B is rotated, the presser will be set in motion.

The'rotation of the shaft B will import an oscillating motion to the arm 2', and the arm m on the same will therefore strike against the bar It, nndas that is, by the lever H, locked to a crank on the shaft G, the said shaft will turn in one direction, and as, at the return more of the bar 2', its lug l strikes against the front of the 18, aka" 2 bar f, the shaft G will be turned-back. Thus oscillating motion will be imparted to the shaft G, and, thereby, reciprocating motion to the PIGSSGXIF. The degree of oscillation of the shaft G can be varied at will, by lengthening orv shortening theconnection of the crank, f, ancl bar h, which can be easily done, as the connecting-lever H is notched, and eesilycontrollable; Thus, if the said connection is long, as in fig. 2, the oscillations will be I considerable, and the presser will he moved for down, so as to compress the clay more then it would were the connection short, as in fig. 4.

By throwing the lever Hquite off the pin g,'the motion of the rock-shaft will be entirely stopped, while that of the shaft B need not he=in the leastinterrupted.

J J are the moulds, operated by a. follower, L,'\ vhichcan be set inunotion by any suitable mechanism. The moulds pass below a grat,'M, in the lower part of the mould-box D, and receive the clay from the mould-box through the apertures-of the grate, and by the action of th c'prosser.

The gl ate is, at its rear end, hinged to the frame of the machine so that its front end is free to swing upward, as indicated in fig. 3. In this manner the moulds can pass out, eve n if obstructions project from them, as in .ig. 3.

The front of the mould-box is closed by an up-end-down sliding gete ,N, which rests by means of pins n 12, upon the front of the grate, and which is consequently raised with the grate, in the manner shown in fig. 3. Bymeons ot' a suitable lever, O, the grate N oanbe forced down again, after the obstructions-hove passed, and thereby the grate will also be forced down again into the original position, the pins to moving it down. The gate N may be secured in a. swinging gate, 0, as shown, or may constitute the only gate of the mould-box, as may be desired. I

I claim as new, nnd'de'sire to secure by Letters Patent-'- 1. The notched her'H, hinged to the loose one It upon theshuft and serving to connect said arm with the crank, f, substantially as described, for the purpose specified.

v 2. The lever 2', having lugs, Z on, fitted loosely upon the roek sheft G, and connected with the main drivingshnft, in combination with the loose arm h,-crank, mdhinged rack-bar H, for the purpose of giving motion 7 to the roek-shnft G, substantially as described.

3. The swinging grate M, in combinntionwith the sliding gate N and the :pins n, all made and operating substantially as herein shown and described.
